Unknown Property Ticks Error on Matplotlib

I ran into an error when I tried to change the label of my x axis to be that of ages_x. Currently, it's x_indexes, which is the length of the ages_x. Here's my code:

import numpy as np
from matplotlib import pyplot as plt


plt.style.use('fivethirtyeight')

ages_x = [25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35]
x_indexes=np.arange(len(ages_x))
width= 0.25

dev_y = [38496, 42000, 46752, 49320, 53200, 56000, 62316, 64928, 67317, 68748, 73752]
plt.bar(x_indexes, dev_y, width=width, color= '#444444', label= 'All Devs')

py_dev_y = [45372, 48876, 53850, 57287, 63016, 65998, 70003, 70000, 71496, 75370, 83640]
plt.bar(x_indexes - width, py_dev_y, width=width,  label= 'Python')

js_dev_y = [37810, 43515, 46823, 49293, 53437, 56373, 62375, 66674, 68745, 68746, 74583]
plt.bar(x_indexes + width, js_dev_y, width=width,  label= 'JavaScript')



plt.title('Median Salary (USD) by Age')
plt.xlabel('Ages')
plt.ylabel('Median Salary (USD)')
plt.legend()
plt.xticks(ticks=x_indexes, labels= ages_x)
plt.tight_layout()


plt.show()

Here's the error:

I think you are using an old verison of Matplotlib

Update to a newer version and your code should run fine. I just ran your code on matplotlib 3.3.2 and it works fine.
